Standard sleep recordings were made on 10 nights over a 3 month period with lights out occurring 20 minutes after drug administration (placebo, 1 gm. l-tryptophan, 3 gms. l-tryptophan). Neither dose of l-tryptophan differed from placebo as to the amount of REM, SWS or wakefulness, but 3 gms. significantly reduced sleep onset latency on some of the nights. Those subjects with latencies longer than 40 mins. had the greatest reduction in latency with 3 gms. and also evidenced high levels of anxiety on the Taylor Manifest Anxiety Scale initially. Subjects with latency between 20 and 40 minutes appeared to receive the longest lasting hypnotic effect from the higher dose. Adaptation to the sleep lab took place across the entire 10 nights of the study.

Eleven (11) participants were requested to operate a driver trainer until they found the task too adverse to continue under conditions of high blood alcohol (BACL greater than 0.08%), low blood alcohol (BACL less than 0.08%), and no blood alcohol. Skill and heart rate were monitored and any personal distresses or observations made about performance were reported to an experimenter who acted in the role of 'passenger'. Results show decline in endurance as blood alcohol increases, but that a higher level of personal distress is endured by drivers who have imbibed, as compared to those who have not. Systematic discrepancies occur between the impressions gained by the experimenter (passenger) from verbal reports made by the driver, and the kinds of self-ratings drivers provide.
